Bombardier hopes it has seen the last of the
software “glitches” that began plaguing the CRJ1000 control-by-wire rudder system early last summer, resulting in the grounding of the pair of prototypes used for flight testing and a certification delay of at least a year.
Flight testing of Bombardier’s new CRJ1000 resumed on February 13, when S/N 19991 took to the air from the company’s Wichita flight-test center, some five months after a second software malfunction prompted the company to completely halt flight testing. In fact, the grounding appeared to have lasted six weeks longer than originally anticipated, judging by the somewhat vague target to resume flying set by Bombardier Aerospace president and COO Guy Hachey during the company’s third-quarter earnings call early last December. At the time, Hachey had said that the company planned to start flying its pair of CRJ1000 test articles “shortly after Christmas.”
